I've seen this on all my machines at boot up since the recent round of updating. Since the consensus seems to be that it is harmless I've ignored it and have experienced no problem of any kind to date. This is still a "YMMV" thing, but I'd bet you can ignore it too. You should know that the ad0/ad1 will result in a fairly drastic performance hit. This is a master/slave arrangement on the same channel. You really really should get another cable and do the ad0/ad2 arrangement. -Mike
